The morphological features are sometimes misapplied to the wrong POS

[vidraj]

Most morphological features we mark are part-of-speech specific. For example, gender is only relevant to nouns and aspect is only relevant to verbs. But due to errors in the techlemma suffixes, some nouns (e.g. “dužnatění”) are marked as imperfective or perfective.

Create a module that checks these basic assumptions (together with various checks on the tree structure, which we don't and possibly can't enforce globally for all languages).
